Ice Storms Cause Havoc Throughout Nation

OKLAHOMA CITY — The ice storms that have been blamed for at least 20 deaths did not abate throughout much of the nation yesterday, as crews tried to restore power to hundreds of thousands and slick roads spawned accidents.

Waves of freezing rain, sleet, and snow since Friday have caused at least 11 deaths in Oklahoma, six in Missouri, two in Texas, and one in New York. Seven adults were killed yesterday near Elk City, Okla., when the minivan they were in hit a slick spot on Interstate 40 and hit a tractor-trailer, the Oklahoma Highway Patrol reported.
